Title: Method and apparatus for controlling the temperature of material being molded
IPC: B29C48/885
Filed: 1965-05-18
Abstract: 1,095,709. Controlling temperature of material being moulded. OWENS-CORNING FIBERGLAS CORPORATION. May 18, 1965 [May 27, 1964], No. 21006/65. Heading B5A. The temperature of material being moulded on the front face of a mould part is controlled by splasher elements which propel droplets of heat exchange liquid against the rear surface of the mould part. In continuously forming a corrugated panel, an unpolymerized rosin layup 30 retained between cellophane membranes is propelled over a tank 34 of heated water to initiate polymerization and gel the resin. The lay-up then passes between a lower corrugated mould plate 40 covering a tank 38 of water at a controlled temperature and the corrugated base 46 of an upper tank 36 of heated water. During the passage of the panel, drops of water are propelled against the rear surface of the plate 40 by rotating splasher paddles 68 to initially provide heat for the polymerization reaction and then as a heat sink to absorb exothermic heat produced by the reaction and prevent monomer boil. The water is circulated in the tank in the opposite direction to the direction of resin feed and passed to a heat exchanger to determine its temperature and action. Each paddle comprises a core 108 enclosed by three tangential rectangular sheets 114 (Fig. 12). The paddles are arranged in rows with their axes parallel and at right angles to the container axis. The two-fold temperature control of moulding processes other than continuous panel production, e.g. using individual moulds moving either continuously or in steps along a production line (Figs. 15 and 16). In another embodiment the invention is used in moulding a boat hull on a stationary mould (Fig. 17).
